Abstract: A luminance compensating method and apparatus for a display device is provided. The luminance compensating method for the display device comprises obtaining a list of first luminance compensation information of the display device set in advance; regenerating target luminance compensation information for all pixels of the display device based on the list of the first luminance compensation information; and performing luminance compensation on input image according to the target luminance compensation information for all the pixels of the display device, wherein the list of the first luminance compensation information is set in advance by dividing all the pixels of the display device into groups, calculating average luminance compensation information for each group of pixels based on initial luminance compensation information of all pixels in this group of pixels, and forming the list of the first luminance compensation information by employing the average luminance compensation information of each group of pixels.
